Električni releji - Preskusi in meritve -56. del: Preskus s krogličnim pritiskom
Ta del standarda IEC 63522 se uporablja za preskušanje, vključno z ustreznimi stopnjami strogosti ter pogoji za meritve in preskuse, ki so bili zasnovani za ocenjevanje zmožnosti delovanja primerkov, v pričakovanih pogojih med transportom in skladiščenjem ter v vseh vidikih operativne uporabe.
Cilj tega preskusa je določiti standardno preskusno metodo za ocenjevanje odpornosti ustreznih materialov na mehanski pritisk pri povišanih temperaturah, ne da bi prišlo do deformacije.
OPOMBA: Preskus se ne izvaja na delih iz keramičnega materiala.
General Information
Overview
EN IEC 63522-56:2025 - "Electrical relays - Tests and measurements - Part 56: Ball Pressure test" (CLC adoption of IEC 63522-56:2025) defines a standardized method to evaluate the resistance of relay materials to mechanical pressure at elevated temperatures. The test helps determine whether polymeric parts used in electrical relays will undergo undue deformation during transportation, storage and normal operational use. Note: the test is not applied to ceramic parts.
Keywords: EN IEC 63522-56:2025, ball pressure test, electrical relays, tests and measurements, relay material testing.
Key topics and technical requirements
- Purpose: Assess material capability to withstand mechanical pressure at elevated temperatures without undue deformation.
- Pre-conditioning: Specimens stored 24 h at 15 °C–35 °C and 45 %–75 % relative humidity before testing.
- Specimen requirements:
- End-product specimens: ≥2.5 mm thickness with approximately parallel faces; planar area at least 10 mm × 10 mm or diameter ≥10 mm. Stacking allowed if surfaces do not move.
- Material (plaque) specimens: produced per ISO methods (ISO 294 series, ISO 293, ISO 295) with thickness 3.0 mm ± 0.5 mm and planar dimensions ≥10 mm.
- Test temperature: Per IEC 63522-10 heating results: test at (20 °C ± 2 °C) + maximum temperature from heating tests, or at least:
- 75 °C ± 2 °C for external parts, or
- 125 °C ± 2 °C for parts that support active parts - whichever is higher.
- Test apparatus & setup: Specimen supported horizontally on a 3 mm steel plate; steel ball 5 mm diameter pressed with force 20 N ± 0.2 N (ball must not move).
- Test cycle: Maintain load for 1 hour at test temperature, remove ball, cool specimen by immersion in water for 10 s (water at reference ambient temperature), then measure impression diameter within 3 minutes to 0.1 mm accuracy.
- Evaluation and reporting: Measure and report impression diameters and test conditions; see EN IEC 63522-56 for required test report elements.
Applications and users
- Who uses it: Relay manufacturers, component suppliers, materials engineers, independent test laboratories, quality assurance teams, and certification bodies.
- Practical uses: Validate material selection for relay housings, insulators and support parts; compare polymer grades for thermal-mechanical stability; demonstrate compliance for product qualification, safety assessments and regulatory certification.
Related standards
- EN IEC 63522-0 (General and guidance for relay tests)
- IEC 63522-10 (heating tests referenced for maximum temperature)
- IEC 60695-10-2 (flame and glow wire test guidance referenced)
- ISO 294 series, ISO 293, ISO 295 (specimen preparation for plastics)
Using EN IEC 63522-56:2025 ensures consistent, repeatable ball pressure testing for relay components and supports reliable material performance claims in demanding thermal and mechanical environments.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as "IEC Publication(s)"). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
any IEC Publicat
